Letters Patent No. 84,623, dated December 1,1868.

' The Schedule referred to in these Letters Patent and making part ofthe same.

To ali whmfi it mwy concern Be it known that I, J 02m GIBBs, ofBrooklyn, E. D., in the county of Kings, and State ofNew York, haveinvented certain new and useful Improvements in Lamp-Burners; and I dohereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the accompanyingdrawings, making a-portion of this specification, in which- Figure 1 isa side view of a lamp-burner constructed according to my invention.

Figure 2 is a veiticaltransverse section of the same.

Figure 3 is a horizontal section of the same, taken in the line a; a: offig. 2.

Figure 4 is a plan View of one portion of the same.

Similar letters of reference indicate corresponding parts in all thefigures.

This invention consists in a movable roller, furnished with an'operating sliding stem, and so combined with the wick-tube, and thefeed-roller of the same,.as to materially facilitate the operation ofraising or lowering the wick in the wick-tube, as circumstances mayrequire. 4

To enable others to understand the nature and construction of myinvention,'I will proceed to describe it. with reference to thedrawings. A represents the main portion of the burner furnished with thewick-tube B, the feed-roller O of which works througha slot in one sidethereof, as shown in figs. 2 and 4, and has its horizontal stem 7 orshaft a projecting out from one side of the burner,

in the usual or any suitable manner.

- Formed in that side of the wick-tube opposite that at which'thefeed-roller (l is situated, is a transverse. slot, 11-, at each end ofwhich there extends outwards stem, 6, which extends out through asuitable hole in one side of the portion, A, of the burner, as shownmore fully in fig. 2, and is furnished at its outer end with a knob, d.By pressing inward this stem, the

rollers 11 are pressed inward through the slot'a. in the wick-tube, andagainstthe wick, shown in red outline in figs. 2 and 4, with any desireddegree of force, whereupon the shaft a, of the feed-roller being turnedin one direction or the other, will be enabled to act .with very greatefliciency upon the wick, to lower or raise the same, as the case maybe.

It will be noticed that when hot pressed inward, as; i

just set forth, the presser-rollers d exert no action upon the wick, sothat the upward flow of the oil in the wick is not interfered with bythe compressionof the same by the feed-roller, as in the burners inordinary use. I

I do not claim the pressure-roller, arranged as described, Whn the sameis controlled and operated by a screw; but

What I claim as new, and desire to secure by Letters Patent, is-e- Thepressure-roller or rollers d, supported in slots 0, when operated by thesliding stem 0, in combination with the feed-roller O, substantially asshown and described.
